The fuel curves, and ignition timing are already set. It takes longer, and may not run right having to RElearn as opposed to just learning.
The biggest thing with doing this is to let it idle for a few minutes to let it set base curves for everything. OBD2 is WAY more toughy about this shit than obd1.
